Fine grains usually form due to rapid cooling
when the lava cools quickley it is fine-grained
A fine grained igneous rock forms from Lava that escapes from the earth crust to the surface and cools and solidifies rapidly.
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
fine grained or coarse grained
Cooling rates. A coarse-grained rock likely cooled slowly, allowing larger crystals to form, while a fine-grained rock probably cooled quickly, resulting in smaller crystals.
A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.
Metamorphic rock can be coarse grained or fine grained.
Limestone can be both coarse-grained and fine-grained, depending on its composition and how it formed. Coarse-grained limestone typically contains larger mineral grains visible to the naked eye, while fine-grained limestone has smaller mineral grains that are not easily seen without magnification.
